Of the versions on Youtube, the verse sung in the cut labeled "original" is best for the tune. Sources used: www.deutschalsfremdsprache.ch http://www.singenundspielen.de/id156_m.htm http://www.volksliederarchiv.de/text553.html

The English is closest to the German original. I think there is a French version that is closer to the original, but the verse about Asti echoes the German in which water is pure as that of a spring or good as Moselle wine. Asti is center of a top wine region. The general idea is the same in both sets of lyrics.
